摘要： A method and corresponding system for operating a dental handpiece, wherein the handpiece comprises a motor for driving a tool. the method comprises (a) sequentially capturing values of a physical parameter, which—at least approximately—represent the power or energy fed to the motor, (b) forming an integration value by integrating the values captured in (a), and (c) automatically reducing a power or energy fed to the motor if the integration value formed in (b) exceeds an upper threshold value. The integration value formed in (b) represents a measure of the power integrated over time and can thus be used at least approximately as a measure of the temperature of the instrument. The automatic reduction in the power or energy fed to the motor performed in (c) can therefore effectively act against a further increase in temperature or allow cooling if the temperature of the instrument exceeds an upper threshold value. In this manner, the risk of damage due to excessive temperature of the instrument can be effectively reduced.

摘要： The invention relates to a control device for the drive of a dental handpiece operated with a regulated electric motor. So that a dentist has an acoustic feedback concerning the loading of a tooth worked with the dental handpiece, the control device is so configured that a speed of rotation characteristic dependent on the load of the electric motor, starting from an initial point, falls with increasing motor current or increasing power, wherein at least one of the initial point, the inclination, and the development of the falling characteristic is selectable.

摘要： A system for driving an electric handpiece in response to a pneumatic control signal may provide for fast interchange of handpieces, self-calibration and wide dynamic range of operation with precise speed control. The system may be incorporated into virtually any dental treatment center using traditional pneumatic drive handpieces, and a conversion kit may facilitate such conversion. The system may provide not only for controlling the speed and torque of a tool coupled to an electric drive handpiece responsive to a pneumatic control signal, it may also provide for coupling cooling air and treatment media, such as air and/or water to the handpiece. Coupling of a handpiece to an operating base of the system, including coupling of media lines and electrical connections may be made with a simple press and twist action using quick connection structure.

摘要： In a method of operating a brushless electric motor, having a permanent magnet rotor and a stator with three windings electrically offset by 120°, provided for example for driving a dental treatment instrument, the zero crossings of a voltage induced by rotation of the rotor in the stator windings is detected by a comparison of a voltage at an inactive stator winding in a monitoring phase with a comparison voltage, and on the basis of the detected zero crossings there is determined the speed of rotation of the motor and/or a suitable commutation point for an intermediate circuit voltage delivered to the stator windings. The comparison voltage is formed by the voltages at the two further, active stator windings in the monitoring phase.
